Top N View in Contrail Command

 
Summary

This topic covers the Top N feature in the Contrail Command GUI.

Contrail Insights has a new Top N or “top talkers” query engine with tabular and charted views. These Contrail Insights diagnostics enable engineers to proactively mitigate issues like network congestion and resource contention.



Contrail Command UI—Top N Feature

Follow the steps to navigate to the Top N View.

  1. Log in to a cluster via Contrail Command by browsing to https://<Contrail-Command-Server-IP-Address>:9091.
  2. Navigate to Infrastructure > Fabrics.
  3. Select the desired Fabric from the available list.
  4. Click on Top N View.

The feature offers table view and chart view.

The default view is the table view.

In addition to the standard Top N results, you can also define custom Top N fields to group the results. Click on the + button to group the results based on different attributes. You can add or remove the desired attributes. The following grouping values are available:

  • Packets

  • Average speed

  • Average number of packets

  • Average size of packets

  • Source IP

  • Destination IP

  • Source Port

  • Destination Port

  • Protocol

  • Source Virtual Network

  • Destination Virtual Network

  • Overlay Source IP

  • Overlay Destination IP

  • Overlay Source Port

  • Overlay Destination Port

  • Overlay Protocol

  • Network Device

  • Source Interface

  • Destination Interface

  • IP Version

  • IP Tos

  • Source ASN

  • Destination ASN

  • Source Network Mask

  • Destination Network Mask

  • Source MAC Address

  • Destination MAC Address

Top N Filter Options

The top–N results show the Top N contributors or “top talkers” to the network traffic and how the Top N contributors change over time. These results are generated from the sampled packets exported by sFlow.

The following network traffic Top N options are available—

Chart View

You can also analyze the Top N results in the chart view.

Click on the Chart View button on the Top N View page.

Click on the Configure button to customize the results.

The following types of charts are available:

  • Bar Chart

  • Pie Chart

  • Donut Chart

  • Treemap

You can customize the Y-axis based on—

  • Bytes

  • Packages

  • Average Packet Size

  • Average Speed

  • Average Packet Number

You can also add heatmap for Y-axis parameters by enabling the option, Custom heatmap. It adds another dimension to the chart view. The option will sort the colors of the chart based on the selected heatmap parameter.

Select the desired fields from the PARAMETERS DISPLAYED list to group the results by various parameters. You can hover your mouse over the chart to see these parameters.

Click Apply to see the results.
